The pistons move up and down when you rotate the gear, simulating the movement of a real V10 engine. Designed for easy 3D printing and simple assembly. The mechanism uses a camshaft instead of traditional connecting rods and a crankshaft, making assembly easier while keeping the pistons functional. Compact, satisfying to play with, and perfect for car enthusiasts, mechanics, and engine lovers!

Material: PLA (Silver, Gunmetal, or Metallic colors look best). Assembly notes: Short assembly videos on Instagram: @artemix2006 All printed parts fit tightly together after printing, ensuring a solid and stable construction.
